Top 10 Light Bulbs a Bright Idea

Did you know?

1. In January 2012, via the 2007 EISA (Energy Independence and Security Act) 100 watt light bulbs will be required to meet new energy standards. New standards will make us be more efficient and will cause less carbon pollution. In January 2013 75 –watt bulbs will be affected and 2014 60-40- watt bulbs. December 31, 2011 will be the last day manufacturers will be able to legally make 100-watt incandescent bulbs for sale.

2. Who invented the incandescent lamp? Historians Robert Friedel and Paul Israel list 22 inventors of incandescent lamps prior to Joseph Swan and Thomas Edison. They conclude that Edison's version in 1879 was able to outstrip the others because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve (by use of the Sprengel pump) and a high resistance that made power distribution from a centralized source economically

3. The bulb Edison invented is going away.

4. If every American home replaced just one light with a light that's earned the ENERGY STAR, we would save enough energy to light 3 million homes for a year, save about $600 million in annual energy costs, and prevent 9 billion pounds of greenhouse gas emissions per year, equivalent to those from about 800,000 cars.

5. New types of bulbs CFL contain small amounts of mercury and precaution should be used if they break and proper disposal is important to protect the environment. Halogen does not contain mercury but is more expensive and it is reported that they do not last as long as LED. Here is a link to an interesting article on LED lights and the cold weather that are currently being replaced and used in traffic lights. It is not that they are a bad idea; just some adjustments need to be made.

6. CFL (Compact Fluorescent Light Bulbs) use 75% less energy then the old standard incandescent.
